CRANK CASE FOR- I NTERNAL-COMBUSTION ENGINES.

Application filed November 18, 1922. Serial No. 601,927.

whereby the sediment collected in a crank.

case may be quickly andthoroughly removed without the removal of the crank case.-

It is also an object of the invention that the crank case be adapted to be: employed in an efficient manner as a retainer for lubricating oil which maybe used for lubricating the engine cylinder and associated parts through the so called splash system]? I Other objects, and objects relating to details of construction, combination and arrangement of parts will hereinafter ap-; pear.

The invention is illustrated by way of example in the accompanying drawings, in

which Figure 1 is a longitudinal sectional view of a crank case when applied and showing the associated crank shaft in side elevation.

Figure 2 is a view in side elevation of a crank case constructed in accordance with resent invention.

Flgures 3 and 4: are sectional views taken substantially on the lines 33 and H respectively of Figure 1.

Referring to the drawings more particularly, S indicates generally the crank shaft of an internal combustion engine, R the connecting rods associated therewith, and C the crank case of the present invention.

The crank case C more specifically consists in a single casting comprisingan elon gated plate 10 corresponding in dimensions to the opening in the bottom of engine hous- 1 ing to which the crank case is to be applied. The plate 10 is provided with a plurality of depressed sections to provide the compartments 12 to serve as reservoirs for lubricating oil. The depressed sections 11 are preferably arcuate in cross section, Figure 3. The compartments communicate with each other through'passages provided by ders and the piston heads.

the tubular formation 13 formed with the casting. I y 7 V The tubular formation 13 communicates with the bottom portion of'each'com'part- 6U ment 12 and the space occurring between plate 10 and the tubular portion at points between adjacent arcuate depressed sections is closed by the integral portions '14. i The tubular formation 13 is slightlyextended 66 at the forward end of casting asat 15, and 1 within the tubular formation there is positioned a rod 16 provided with a head 17 at its rear end which corresponds in diame-' ter to-the interior diameter of .tubular 1 formation. The other'end of the rod may a be threaded and'carry a bushing, said bushing comprising a head 18 and a reduced threaded portion 18 which is threadedinto the associated end of extension 13 sothat a tight closure of'the extension maybe had. The rod also-carries a plurality of washjers 19, one'occurring between each of the compartments 12 and adapted to effect a j closure of the passageformed by the tubular formation 13, The washersl9 are held in proper spaced relation by sleeves 19' and these sleeves are clamped between the bushing 18 and head 17.

In the use of the present may be secured to the ordinary housing of 1 an internal combustion engine, as illustrated in Figure 1 of the drawings. The diflerent compartments 12 may be filled with a suitable lubricating oil and these compartments may be, brought into proper alignment as,

illustrated -so that the crank shaft'of the associated engine will strike the oil during rotation thereof and splash the same forv lubricating the internal walls of the cylin- The tubular formation 13 to a certain extent aids in agitating the oil within the chambers 12'for lubricating the parts of the associated engine, which is thought to be obvious.

When it is desired to drain the oil from the different compartments 12, the rod 16 to gether with the sleeves 19 and washers 19 are removed and the oil permitted to .run from the compartments through the. openings formed by said tubular formation. Upon removing the rod the washers or col- 7 lars 19 will draw therewith sediment which may have collected in the different compartments 12 and in this way cleaning the crank-case. The casting provided by this invention is sometimes referred to as an indevice, the same 86 spection plate, however, in the present ap pllcat-ion 1t has been designated as acrankcase.

While I have shown and described the preferred form of my invention, 1 Wish it to be understood that I am aware of the fact, that the construction, combination and arrangement of parts may be changed by those skilled in the art WltllOllt' departing from the spirit of the invention, as indicated by the appended claims. 1

I claim: 7 V 1 1.- In' combination With an engine, a crank-case having compartments extending transversely thereof and communicating through different passages, said passages being in longitudinal alignment, arod extending through said passages and having Washer means for closing the passages between said compartments.

2. In combination With an engine, a crankcase having compartments extending transversely thereof and communicating through different passages, said passages being in longitudinal alignment, a rod extending through said passages and having Washer means for closing the passages be-. tween sald compartments, said rod also be ing adapted When Withdrawn fromthe crank-case to permit liquid Within the differentcompartments to drain from the crank case.

In combination with an engine, a

transversely thereof, and-- communicating through aligned passages, a rod extendingthrough said passages of smaller diameter than the passages, and means carried by the rod whereby the passages maybe closed, for r the purpose described I i. in combination With an engine, a crank case having compartments extending transversely thereof and communicating through aligned passages, and an end compartment '2 having a passage extending through its outer Wall, whereby to drain the crank case and the last-named passagebeing in longi-* tudinal alignment With the first-named passages, a rod extending through the difierent passages and carrying'means whereby said aligned passages,'and an end compartment having a passage in its outer 'Wall adapted to drain said crank case and also in longi;

tudinal alignment With the first-named passages, a rod extended into said passages;

means carried by the rod adapted to close each of the passages, and a nut threaded, upon'the one end or" saidrod and adaptedf to be threaded into the associated end of the crankcase, whereby to lock the rod-against removal.
